The Power of the Papacy

The Power of the Papacy during the Crusades (c.1095-1149)

Foundations and Development

  • Urban II played a vital role in initiating the First Crusade, using a Papal Bull to promote the campaign.
  • This move significantly increased the Pope’s power, both spiritually and politically, as it allowed him to unify Catholic Europe under one holy cause.
  • Later Popes further capitalised on the prestige and influence achieved through the success of the Crusades.

Spiritual Influence

  • The Papacy held significant spiritual power, as Catholics believed the Pope was God’s representative on earth.
  • Indulgences were introduced by the Pope as a way to encourage crusaders. These were forms of pardon that removed the kind of penance required for sins.
  • The Popes’ declarations of Crusade, known as bulls, emphasised this spiritual power and united the people of Catholic Europe.

Political Power

  • The Pope could exert influence over the monarchs and lords of Europe, requiring their fealty and service for the Crusades.
  • This established the idea of Papal Supremacy, where the Pope had ultimate authority over all Christian governments.
  • The Pope also had the power to excommunicate individuals who disagreed with his mandates, which was a powerful tool for maintaining political control and unity of the Crusades.

The Papacy’s Changing Power Post-Crusades

  • The successes and failures of the Crusades greatly affected the Pope’s power. Successful campaigns boosted their authority, but failures could cause it to decline.
  • The dramatic results of later Crusades - particularly the Sack of Constantinople during the Fourth Crusade - led to a significant fall in the perceived authority of the Papacy.
  • By the end of the Crusading period, the Papal States had been established, effectively making the Pope also a secular ruler in addition to his religious duties. However, the concept of Papal Supremacy was increasingly challenged by various European rulers.
